We sown different types 28 maize lines at Anand Agriclutural University Anand, Gujarat at December 8 as a part of our departmental work. Out of 28, 14 are composites, 5 are QPM inbreed lines, 5 are normal/local inbreed lines and 4 are PFSR lines! Actually the date of sowing was very late! I observed that those genotypes, blooms early shows differences in their expression in flower colours! Because that time means just after 60 days of sowing flowers face the last phase of winter season in Gujarat. Might be that's why the anthocyanin pigmentation expression varies from plant to plant within the same lines! Difference in expression was occurred in glumes, anthers, at the base, in silk, at brace root and on stem also! According to DUS criteria pigmentation expression helps to separate the lines or entries! But the variation was noted in not only in between the lines but also within the lines! So like wise, I want to know the other traits which expression changes during G x EE influence in case of maize crop!
